I thought you could pop out a window in OF pro. Is that possible?
you can create a new window or lots more windows by holding option/cmd N. Is that what you mean? You can also merge all open windows in tabs in the menu bar by using window sub menu ‘merge all windows’.
If you mean when you select a perspective that has open in new window checked, it doesn’t seem to respect that selection if you click on it from the side bar via the mouse. If you assign it a keyboard shortcut or select it from the Perspectives menu it will open a new window.
